Hi Priscilla,
As a Londoner who has lived in the UK for over 20 years, I would as from my own experience and to save a lot of money from your monthly salary to do your grocery shopping at Lidl supermarket ( it id very good quality for money and this is a German brand with high quality products), also do the rest id your grocery shopping like poultry, meat, fish, various products like rice, plantain bananas, fan, vegetables and other good products at London stall markets like East Street Market in Walworth Road or Brixton Market or Borough Market.But I would recommend more Brixton Market as you have more verify of things and choices.Also on Walworth Road opposite the MC Donald across the road you will see a £1 shop called Sam 99 where absolutely every item you buy just costs £1.There are similar £1 shops across London and id id always quality stuff.
You can also go down the Elephant and Castle area and on the lowerground floor find another £1 shop as well.
If you want to buy appliances for your home and kitchen you can go to Argos and they have many stores across London.www.argos.co.uk .
Now coming into the accommodation side id things, it id always expensive in London.
I would advise you to use the following newspaper called Loot (it is pink unless the color changed over the years) and check their accommodation section.
Depending on the area where you will becsetlled, I would advise as well to find out where the local council housing office is located, and full in with them a council housing application. It can take years until you get offered accommodation with them but it is still worth it, because local council accommodation cost a lot cheaper than those in meantream accommodation. For example for a one bedroom flat that would cost £900 per month on the high street, the same type of accommodation with the local council housing will cost around £60 per week less local council tax (kind id housing tax) that you pay monthly but them again it is not sky rocketing.
When I first arrived in London from Paris, I was lucky to have next of kin already established in London, so I did not have a specific budget with hr as they offered me free accommodation for over 6 months, until I could get to know the system, get a job and have my iwn place.
But as a whole I would recommend that you have with you at least £2000 to be on the safe side to start with.
Also another way to look for accommodation is to check shop windows kept by people from Pakistan and India, as there are lots of ads placed on them by people who have a accommodation to rent out.
I hope that I have not forgotten any of your questions.Feel free to contact me idfyou need more information about settling down in London.
Regards,
Jotace
